除了单纯的处理Excel数据外,还可以将Excel中的合并项、公式项、单元格格式提取,提取后可根据业务需求做对应处理后存储起来,以便后续的各种操作。

将数据处理好后,可以通过额外配置,将导出的Excel做各种不同的配置,例如打印样式、锁定行、背景色、宽度等。
/**

*
* @param array $datas 导出数据,格式['A1' => 'XXXX公司报表', 'B1' => '序号']
* @param string $fileName 导出文件名称
* @param array $options 操作选项,例如:
* bool print 设置打印格式
* string freezePane 锁定行数,例如表头为第一行,则锁定表头输入A2
* array setARGB 设置背景色,例如['A1', 'C1']
* array setWidth 设置宽度,例如['A' => 30, 'C' => 20]
* bool setBorder 设置单元格边框
* array mergeCells 设置合并单元格,例如['A1:J1' => 'A1:J1']
* array formula 设置公式,例如['F2' => '=IF(D2>0,E42/D2,0)']
* array format 设置格式,整列设置,例如['A' => 'General']
* array alignCenter 设置居中样式,例如['A1', 'A2']
* array bold 设置加粗样式,例如['A1', 'A2']
* string savePath 保存路径,设置后则文件保存到服务器,不通过浏览器下载
